Against the backdrop of rising fuel prices and increasing demand for transport fuels, coupled with government’s imperative to reduce high unemployment levels by developing the agricultural sector to support a bio-fuels sector, it was considered necessary to conduct research to determine the factors that would influence the success of bio-ethanol production for use in liquid transport fuels. The literature review highlighted five key factors that were developed into research questions to establish whether these factors are relevant to the South African context and which are considered more important. The research was conducted using a combination of face-to-face interviews and telephonic interviews to gather opinions from 16 subject matter experts in the field of bio-fuels. A questionnaire was used to drill down into each of the factors individually, to determine the importance of that factor as it relates to bio-ethanol production. The findings reveal that the absence of clear and sound government policy poses the biggest hindrance to the establishment of the industry. Furthermore, that agricultural development is a major factor for the success of bio-ethanol production as the industry is dependant on the availability of competitive feed stocks in order to be sustainable. Finally, that job creation is the motivating factor for the establishment of the industry since it addresses a government imperative to reduce unemployment levels in South Africa. / Dissertation (MBA)--University of Pretoria, 2007. / Gordon Institute of Business Science (GIBS) / unrestricted

Interactions between certain fuel sulfur compounds and nitric oxide (NO) in turbulent gaseous and distillate oill diffusion flames were experimentally investigated utilizing a 75,000 Btu/hr laboratory combustor. Aerodynamics, air preheat conditions, and overall excess air conditions were varied to determine their role on any such interaction. Results indicated that addition of sulfur dioxide (SO₂) to natural gas flames could enhance or inhibit NO emissions. Local flame stoichiometry and temperature, which were influenced by fuel injector type, determined which effect was observed and the extent to which it occurred. Thiophen (C₄H₄S) and pyridine (C₅H₅N) were added to #2 diesel oil to determine effects of fuel sulfur on conversion of chemically bound fuel nitrogen to No. No discernible effect was observed at "zero" air preheat conditions. No emissions were enhanced at high air preheat conditions. Addition of SO₂ to natural gas flames doped with ammonia (NH₃) produced a significant increase in conversion of NH₃ to NO at high air preheat conditions. Inhibition effects were explained in terms of homogeneous catalysis of recombination reactions by SO₂. Hydrogen abstraction reactions involving reduced sulfur species and other oxidation reactions involving SO₂, or a reduced form, were considered to explain the enhancement effect.
